The Methane Content of Coalbeds in Region III.
Symp Methane Gas from Coalbeds: Dev prod and Util DOE MERC/SP- 78/1 1978 Jan; :5-7
The deep bituminous coalbeds of region III, with an estimated 150 billion tons of coal, probably contain at least 30 trillion cubic feet of methane. Bureau of Mines research has demonstrated that it is possible to recover pipeline-quality gas from several bituminous coalbeds in region III for less than $0.50 Per thousand cubic feet. Ultimately, most of the gas can be recovered from the deepest coalbeds at costs that are well below the $3.25 to $4.50 Per million btu that lng imported from algeria will cost. More than 2 billion cubic feet of gas has already been drained from coalbeds in Region III in Bureau experiments and demonstrations; an additional 250 million cubic feet have been drained by others using similar techniques. The 20 billion tons of anthracite in eastern Pennsylvania may contain an additional 4 to 6 trillion cubic feet of methane. However, preliminary tests indicate that commercial production is not now feasible from anthracite.
